Why Do Granite Countertops Need To Be Sealed?

While granite is one the most durable countertops options, it does require some maintenance to keep its beauty and resilience, which includes sealing the granite. Without a proper seal, granite can collect moisture and germs, making your food preparation area unsanitary.

Reasons You Need to Seal Your Granite Countertops

Stone sealer is one of the most important parts of your granite countertop maintenance. It will keep your counters looking great and will also protect the granite from stains, scratches, and dullness.

Although granite is a durable stone for countertops, if it is left unsealed, it can lead to damage such as:

  • Deterioration from acidic substances.
  • Etching that is caused by vinegar, lemon juice, or acidic cleaners
  • Staining from food or drinks such as coffee or wine.
  • Without sealant, your countertops can also become stained by water that penetrates the surface. Additionally, certain cleaners and chemicals can erode the surface and seep into the stone, causing damage to the color and the finish.

Signs Your Granite Countertops Need to be Resealed

Typically, if your countertops are ready to be resealed, they will have dull spots. Your countertops should be glossy, so if there are dull spots, it’s time to reseal them.

You can also test them by placing a couple of drops of water on your granite countertops and letting them sit for 30 minutes. If the water has been absorbed into the surface of the countertop, then it will need to be resealed.

How Often Do Granite Countertops Need to Be Resealed?

We recommend that you reseal your granite countertops at least once a year, but the frequency will depend on how often you use your countertops. If you cook frequently and use your countertops every day, then you may need to reseal your granite more often.

In addition to the frequency of use, the type of sealant you use will also affect how often you will need to reseal the granite. Some sealants on the market last longer than others. It is crucial to look for a sealant that has advanced chemical technology. This will allow the sealant to form a more permanent bond with the stone.

While these long-lasting sealants can be more expensive, they will last much longer than others, either lasting for years or indefinitely. One sealant that we recommend is the Stonetech Bullet Proof Sealant by DuPont. This is a high-grade sealant that is supposed to last for at least three years on indoor countertops.
